(I am working in the electronics section of a store. A customer approaches me to get a calculator for doing taxes. I ensure she has a decently priced calculator, two rolls of paper and extra batteries since she doesn’t have a power adapter. She leaves happily. A few hours later, she returns.)

Customer:*holds the calculator like a hurt puppy* “Something is wrong with the calculator.”

Me: “Oh, I am sorry to hear that. What seems to be wrong?”

Customer: “The display doesn’t seem to be working. I wanted to see about a refund, if possible.”

Me: “Sure, let me take a look at it.”

(I begin to take a look over the calculator, checking things like ensuring the batteries are inserted properly, that there’s no visible damage to the casing, and that the calculator had been switched to the “on” position. My eyes wander to the display, and then I look back at her.)

Me: “I can see why the display isn’t working.”

Customer: “Oh, good! Could you fix it?”

(I remove the demo sticker that goes over the display, and hold out the now-working calculator to the customer.)
